KIRKERSVILLE, Ohio — An Ohio police chief was fatally shot by a gunman who then opened fire in a nursing home Friday morning, killing two others before turning the gun on himself, reports CBS affiliate WBNS.

Ohio State Highway Patrol Lt. Robert Sellers says Friday that the situation has ended and there is no threat to the public.

Disario, 36, had only been on the job for about three weeks, Thorp said. He said the chief was the father of six children, with a seventh on the way.

“It’s a hard day for all of us,” Thorp said.

Disario was responding to a report of a man with a gun, and his last radio communication said he had the suspect in sight, Thorp said.

Responding officers found Disario on the street and then investigated a report of a gunman in the nearby Pine Kirk Care Center, Thorp said.

Two employees of the center and the suspected gunman were found dead inside the nursing home, the sheriff said.

He said police weren’t immediately able to positively identify the gunman and were trying to determine what, if any, relationship he had with the nursing home.

A local elementary school was put on lockdown, and parents were later told they could pick up their children at a nearby middle school.

The shooting closed down the main street in the village, which was flooded with police officers from several surrounding agencies and with ambulances. The village of about 500 residents is roughly 25 miles east of Columbus.
